I know I said I was done replying to this thread but I just cant keep my mouth shut. I think people need to back off this guy and let him learn the hard way. Let him think his miracle solution will work, and let him post his "positive update" posts. We should all just sit back and let him deal with it; its not our problem.
HE DOES NOT LISTEN TO ANYONE, so IMO we should not attempt to help anymore. I also think we shouldn't be as harsh on him only because all it will do is get the thread locked. Let's all play nice now and get a good chuckle out of it. I'm not saying that what he is doing is funny because it's not. The funny part of this thread is his inability to face the facts and do things the right way. It's not cool to let these fish die, but in all reality its HIS fish... There's plenty more in the ocean.
Yet I would like to point out some things to jadendo:
1)
YOU DONT LISTEN
2) your tank is too small by far
3) the people replying to this thread are only trying to help
4)
YOU DONT LISTEN 
5) it does not take "years" for fish to grow fast. This is a picture(s) of a tang that I own for 5 months....
Years...? Common man, your
way off.
6)
NEVER go back to ANY of the stores that are selling you over-sized fish, hard to keep corals, magic medicine, and accept no returns. That's
100% complete nonsense on there part
7) Oh, and
YOU DONT LISTEN.

If you haven't even made an attempt to try the things suggested on this thread. If you did then maybe people wouldn't be as harsh.
End rant and again, Best wishes
